JOHN F. HAUQUITZ, OF IDAHO SPRINGS, COLORADO.

SHIM.

Specification of Letters Patent.

Application filed June 28, 1911.

Patented July 23, 1912.

Serial No. 635,721.

To all whom it may concern:

Be it known that 1, JOHN F. HAUQUITZ, a citizen of the United States,residing at Idaho Springs, in the county of Clear Creek and State ofColorado, have invented certain new and useful Improvements in Shims. ofwhich the following is a specification.

My invention relates to improvements in shims and has for its leadingobject the provision of animproved device of tl is char acter by the useof which a cylindrical shaft such as the shaft of a crusher stamp stemmay be readily secured and wedged into place within a socket having atapering wall.

A further object of my invention is the provision of a device by the useof which a cylindrical member may be caused to fit tightly into aninwardly tapering socket and be secur ely held in said socket withoutnecessitating the. changing of the size or shape of the shaft or stem inany manner, the object also being the provision of a device by the useof which jars or shocks against the free end of the shaft or stem to besecured in position will serve to tighten the grip of the retaining andadapting wedge instead of loosening the same as is the. case whenordinary wedges are employcd.

Other objects and advantages of my im 'proved shim will be readilunderstood by reference to the following escription taken in connectionwith the accompanying draw: ings, and it will be further understood thatI may make any modifications in the spe ific structure shown anddescribed within the scope of my claim without departing from orexceeding the spirit of my invention.

Figure 1 represents a sectional view llt)\\ ing my device in use insecuring a stamp stem within a boss head. Fig. 2 represents a top planview of my device. Fig. 3 repre sents a bottom plan view thereof, Fig.4,

represents a perspective view of the saint; In the draw tngs, thenumeral 1 designat a boss head or member provided with the L My deviceas best shown in Fig. 4, comprises a substantially cylindrical sleeve 4having the round bore 5 and having its outer face slightly or decidedlytapering toward one end, the inclination of the face 6 depending uponthe tapering of the socket into which my device is adapted to fit. Mydevice is closed at its smaller end by the end plate 7 formed integraltherewith, while to permit of the diameter of the bore 5 being slightlyvaried in order that the shaft or stem 3 may be easily inserted and willbe afterward clampingly retained by my device when the end of the shaftor stem on which my device is fitted is forced into the socket 2, 1 formin one side of the portion 4, the longitudinally extending slot 8 withits edges slightly spaced from each other, while I further form in theend or cap plate 7 the slot J which is a continuation of the slot 8 andextends across the cap plate diametrically almost to the opposite sideof the sleeve 4 from that. in which the slot 8 is formed. It will thusbe seen that. the slot 8 and the slot 9 together permit both of the sizeof the sleeve 4 at its open outer end and at its closed smaller innerend being varied to allow the same to be cammed or pressed into tightengagement with the cylindrical shaft or stem, while to further increasethe resiliency of the portion 4 and enable it to be more readily sprunginto clamping engagement with the stem, l form in said cylindricalportion at points equidistant from the slot 8 the slots 10. said slots10, however,

extending nearly to the base or end plate 7 and not cuttingthercthrough.

From the foregoing description taken in connection with the drawings theconstruction of my improved device will be readily understood, and itwill be seen that the end of the stem 3 rests against the end plate 7ant. serves to force the device into the socket 2, while theengagen'ient of the internally tapered walls of the socket with inwardlytapering socket 2 into which 1 my improved device for securing the cylinl i i the exteriorly tapered face 6 of my device serves to spring theslotted portions of my device against the stem to wedgingly lock dricalshaft 3 in position within the socket 2. l the same within the socket.
